The first remains were described in 1999 based on several skeletal elements uncovered in the three years preceding. ... but this may do with the sparse nature of the remains and the small sample size (the small sample size must be kept in mind of any phylogenetic discussion based on the described traits). This is in the Middle Awash of Ethiopia's Afar Depression. Although the intelligence of these early hominines was likely no more sophisticated than modern apes, the bipedal stature is the key evidence which distinguishes the group from previous primates who are quadrupeds. Fifteen years later, the rest of the skeleton was found at the same location at Sterkfontein (Silberburg Grotto) and matched to the p… Some scientists claim that the large molar teeth show that Australopithecus garhi is related to Paranthropus aethiopicus; however, the combination of features of the face, braincase, and teeth are unlike Paranthropus. garhi is important because it may be … Australopithecus garhi is a 2.5-million-year-old gracile australopithecine species whose fossils were discovered in 1996 by a research team led by Ethiopian paleontologist Berhane Asfaw and Tim White, an American paleontologist.

The hominin remains are believed to be a human ancestor species and possibly the direct ancestor to the human genus, Homo. The ape-like Australopithecus sediba was first discovered near … All of the above. However, further evidence may help anthropologists and scientists to determine the true ancestor species. "With the addition of A. garhi to the inventory," Rightmire said, "there are more species of Australopithecus than one can shake a stick at. A. garhi's remains have been found with tools and butchered animal remains, suggesting the incipience of a very primitive tool industry. Two types of australopithecines were using two different types of locomotion in East Africa: one was a climber and the other a biped. It is evident from the remains of the extinct species that closely resemble the genus homo (Asfaw, Berhane, et al 630). Garhi is ancestral to Homo (i.e. Join now. More surprisingly, they found nearby evidence that the creature, named Australopithecus garhi, butchered and ate meat 2.5 million years ago. Discovery. Q 33 Q 33. analysis (Strait et al., 1997) was updated to account for recent fossil hominid. This close temporal association has led some to suggest that it is the ancestor of our genus, although the lack of distinct Homo -like traits make this far from certain. afarensis derive from Hadar, a site in Ethiopia’s Afar Triangle. The fossil record seems to indicate that Australopithecus is the common ancestor of the distinct group of hominines, now called Paranthropus (the "robust australopithecines"), and most likely the genus Homo which includes modern humans. A very early hominin species has been ruled out as a direct ancestor of Homo sapiens..
